TECAPET TF grey is a PET polyester that has been modified with PTFE additive, to improve its wear characteristics. The material is suitable to be used in many areas in the food processing industry, as it carries all necessary compliances for direct food contact. The addition of PTFE as a solid lubricant, allows for this PET material to demonstrate excellent sliding properties in addition to excellent wear characteristics, as well as the familiar physical properties inherant to standard TECAPET PET polyester material.
